I'm getting following error with the above code

 

Compiling...

DX.cpp

Linking...

..\Program Files\Microsoft DirectX SDK (November 2007)\Lib\x64\d3d9.lib : fatal error LNK1113: invalid machine type

Error executing link.exe.

 

DX.exe - 1 error(s), 0 warning(s)

I have included "lib and include directx directories" in the project.

Pls tell me abt this error and how to correct it.

 

Any help will be appreciated

it looks like you referenced the x64 Direct X libraries -- are you on a windows 64bit machine?
